Officer Robert Stump, 31, remained in critical condition as of 2 p.m. Tuesday, according to a Sparrow Hospital spokesperson. He was responding to a suicidal subject about 5 a.m. Monday when he failed to negotiate a curve along Herbison Road west of Schavey road. His patrol vehicle struck trees and a utility pole.

DeWitt Township Police Chief Brian Russell said Stump is doing better Tuesday than Monday but still has a long road to recovery ahead of him.

"We heard he was improving a little bit," Russell said. "He has a lot of family support there, so everything's good that way. We'll be there in a heartbeat if he needs us."

Stump, who has served with the DeWitt Township Police Department for four-and-a-half years, had to be cut out of his 2012 Ford SUV by emergency crews, Russell said. Heavy fog in the area Monday morning was a suspected factor in the crash.

Russell said his agency has turned its investigation of the accident over to the Clinton County Sheriff's Office, whose accident investigators could complete their report within one week.
